Jeep J10 pickup

The Gladiator name was dropped after 1971, after which the line was known simply as the Jeep pickup. The pickups were designated as J2000 and J4000 models (the 3000 series was dropped in 1971) until 1973, then as J10 and J20 models from 1974 to 1988.

Engines:

From 1971 to 1972 Jeep pickups offered the AMC 304 cu in (5.0 L) 210 hp (157 kW; 213 PS) V8 as an optional engine.

The AMC 258 cu in (4.2 L) I6 engine was introduced in 1972 and offered through 1988. The engine produced 112 hp (84 kW; 114 PS) and 210 lb·ft (285 N·m) of torque.

The AMC 360 cu in (5.9L) was offered in 1971 and through 1988. Producing in early versions 175 hp (130 kW; 177 PS) and 245 lb·ft (332 N·m) of torque. Later 360s produced 195 hp (145 kW; 198 PS) and 295 lb·ft (400 N·m) of torque.

The model designations were simplified for 1974, with the J-2000 becoming the J-10 and the J-4000 changed to J-20. Larger brakes were made standard and the turning radius reduced. The Quadra-Trac system was now available with all engines.^[1]

The AMC 401 cu in (6.6 L) was offered from 1974 through 1978. These engines are known for their toughness and excellent power output. The 401 produced 225 hp (168 kW; 228 PS) and 320 lb·ft (434 N·m) of torque.

For 1977, Jeep J-10 pickups included Dana's manual four-wheel-drive system, a more powerful 258 cu in (4.2 L) six-cylinder engine, and heavier axle tubes, while power front disc brakes became standard equipment and the considerably greater GWV capacity J-20s included AMC's 360 cu in (5.9 L) V8 engine.^[3] The 401 cu in (6.6 L) engine was optional, as well as full-time Quadra-Trac and both automatic and manual transmissions.

1983 saw the new full-time four-wheel drive system, Selec-Trac, replace Quadra-Trac;

Chrysler bought out AMC in 1987. The full-size Jeep Pickup line was not only an aging model, but also competed directly with the broader range of Dodge trucks. Chrysler discontinued the full-size Jeep trucks, but continued to build the luxurious and highly profitable Grand Wagoneer, which shared the chassis with the large pickups.

After the Chrysler buyout, the compact Jeep Comanche pickup (based on the Jeep Cherokee (XJ) platform) received only minor changes and its production continued until 1992.^[4]
